Our customers rely on Reality Defender to make high-stakes calls in real time — whether the voice on a bank's phone line or the face in a job interview is real. As a Quality Assurance Engineer, you'll make sure what we ship holds up to that standard, testing our APIs, SDKs, web app, and real-time integrations, and building the automation that lets us release faster without breaking things. This is a full-time role based at our NYC headquarters or remote within the U.S., reporting to Quality Assurance Lead. Responsibilities include:

• Own test planning and execution for assigned product areas — APIs, SDKs, the web app, and real-time voice and video integrations — from requirements review through release sign-off.
• Build and maintain automated test suites (API, end-to-end, and regression) and integrate them into our CI/CD pipelines.
• Find, document, and track defects with clear reproduction steps, severity, and impact, and work with engineers through to resolution.
• Test the reliability and performance of real-time detection under realistic conditions — latency, load, varied audio and video quality, and different platforms and devices.
• Help maintain the test data and media sets used to validate each release.
• Partner with the AI Research and Red Team to support model release validation and regression testing.
• Help Customer Support and Solutions Engineering reproduce and triage customer-reported issues.
• Contribute to QA standards, documentation, and release checklists across the engineering team. WHO YOU ARE.
• 3+ years of experience in software QA or quality engineering, testing web applications and APIs in a fast-moving release environment.
• Hands-on experience writing automated tests in Python, JavaScript/TypeScript, or similar, using frameworks such as Pytest, Playwright, Cypress, or Selenium.
• Experience testing REST APIs (e.g., Postman or code-based API tests) and working within CI/CD pipelines (e.g., GitHub Actions).
• Strong attention to detail and a systematic approach to finding edge cases — you think about how things break, not just whether they work.
• Clear written communication: your bug reports and test plans are easy for engineers to act on.
• Experience testing audio, video, or real-time communication products (WebRTC, telephony, conferencing). (nice to have)
• Experience testing ML-powered products or working with test datasets. (nice to have)
• Exposure to performance or load testing tools (e.g., k6, Locust, JMeter). (nice to have) WITHIN 12 MONTHS, YOU'LL…
• Own QA for multiple product areas with minimal oversight.
• Have helped establish quality metrics (escaped defects, coverage, release stability) that the team tracks and acts on.
• Be improving QA tooling and practices beyond your own areas.
• Be ready to take on broader scope and mentor newer QA team members. WHAT WE OFFER. Reality Defender offers the following benefits to all our employees, regardless of location:
